DVD copyimg problem

[bkjeell]

Trying to copy a movie (Jayne Mansfield's Car) and get this error message:

MakeMKV v1.8.10 darwin(x86-release) started

The movie plays with no problem on the Mac (iMac OSX 10.9.2) and I have tried to copy it as well with Wondershare Video Converter Ultimate with no problems. Also MacDVDRipper Pro can copy the DVD without any problems.
I am using an external Blue-Ray DVD Samsung Model: BD-RE TSSTcorp BDDVDW SE-506BB TS00

Any ideas?
thnx

Is the drive connected via USB? Is it a port-powered (no separate, external power connector) drive? If not, ignore the rest of this message.

The error you are receiving is characteristic of a drive that is not getting enough power when it reaches full speed, and the drive stops responding to the operating system commands. Programs that do not spin the drive to its full capacity do not experience the problem; sometimes, MakeMKV is just too efficient for the hardware.

The usual fix is to make sure the drive has full power available. They will sometimes have "two headed" USB cables, to get sufficient power. If you are plugged into a USB hub, make sure the hub has sufficient power. Un-powered hubs are a definite no-no for port-powered drives, so either plug into the computer itself, or use a hub that has a power supply that provides at least .5amp for EACH port in the hub.
